These office retailers will all be destroyed unless they fundamentally change how they do business.

The biggest threat is the fact that workplaces are going digital, making the decline of the office supply industry a reality.

"All three companies [OfficeMax, Office Depot, and Staples] could soon face an even larger existential threat than Amazon," wrote Ryu Spaeth at The Week. "The rapid digitalization of a workforce that has grown less reliant on notepads, pens, and printers. And that may be a trend no merger can solve."

The shift to the paper-free cloud is not only affecting paper and printers.

It also means that people don't need mega-packs of highlighters, because they're going through data on their iPad. They don't have to buy pens to jot down notes, because they're typing them out on Evernote. They don't need staplers, because a file on a computer monitor doesn't need to be stapled.

"This is a cloud- and tablet-based and paper-free world," wrote Cody Willard at MarketWatch. "We’re already there, and all those trends are only going to get bigger."

Here's a chart of percentage change in jobs in various retail segments that Thompson got from EMSI. All of the segments worse off than office stores have been infamously decimated in recent years and office stores are poised to follow:

We've already seen consolidation among big boxes with the death of once-mighty CompUSA, Circuit City, Borders, Linens N' Things, and others. K-Mart continues to close stores like crazy. Department stores are getting slammed too — jobs in that sector are down more than 40 percent since 2001, according to the data from EMSI.

An Office Depot exec acknowledged the need for change back in 2011, saying, “Our customers have spoken loud and clear: The big box era is over for them, they value convenience and speed, and they are voting with their wallet."

But it won't be enough to reduce store square-footage. Small stores with all the same products aren't going to suddenly make workplaces revert to the old ways.

And it won't be enough to change the product assortment away from stacks of paper notepads and manila folders if margins are being tightened due to money wasted on unneeded store space.

The current model will implode, and there's nothing anyone can do to stop it. It's the end of the office supply retail world as we know it and these retailers will have to make radical transformations in both areas if they want to survive.
